N2 - Background: Chronic obstructive pulmonary disease (COPD) is a progressive disease and a composite endpoint could be an indicator of treatment effect on disease worsening. This post-hoc analysis assessed whether indacaterol/glycopyrronium (IND/GLY) 110/50 μg once daily reduced the risk of clinically important deterioration (CID) versus salmeterol/fluticasone (SFC) 50/500 μg twice daily in moderate-to-very severe COPD patients from the FLAME study. Methods: CID was defined as ≥100 mL decrease in forced expiratory volume in 1 s (FEV1) or ≥ 4-unit increase in St. George's Respiratory Questionnaire (SGRQ) total score or a moderate-to-severe COPD exacerbation. Changes from baseline in the rate of moderate and severe exacerbations, time to first moderate-to-severe exacerbation, and change from baseline in the SGRQ score, measured after Week 12 up to Week 52, were assessed by presence of early CID (CID+) or absence of CID (CID-) at Week 12. Results: IND/GLY significantly delayed the time to CID (hazard ratio [HR] (95% confidence interval [CI]), 0.72 [0.67-0.78]; P < 0.0001), and reduced the incidences of CID versus SFC. Additionally, IND/GLY delayed the time to CID in all patient subgroups. After 12 weeks until 52 weeks, CID+ patients had a significantly higher rate of moderate-to-severe exacerbations versus CID- patients (P < 0.0001); moreover, CID+ patients experienced moderate-to-severe exacerbations significantly earlier versus CID- patients (P < 0.0001). CID+ patients had a comparable change in the SGRQ total score versus CID- patients. Conclusions: IND/GLY reduced the risk of CID versus SFC. CID had a significant impact on long-term exacerbation outcomes in patients with moderate-to-very severe COPD and a history of ≥1 exacerbations in the previous year.
